1 OWNER S MANUAL Thompson Valve 1 IMPORTANT WARNING FOR SAFER BLAST CLEANING 1. Use protective equipment: Abrasive-resistant clothing, safety shoes, leather gloves, ear protection, CE-approved air-fed helmet. Air for helmet must be supplied by a breathing air compressor or through a helmet air filter. 2. Check for possible silicosis hazards. Avoid dust. 3. Do not blast with damaged or worn equipment. 4. Point nozzle only at area being cleaned. 5. Use only proper dry and well-screened abrasives specifically intended for blasting. 6. Keep unprotected workers out of the blast area. 7. Before blasting: - Check fittings and hose for wear. - Safety-wire couplings together. - Check helmet filters and air supply. - Check pop-up valve for alignment. - Test remote controls. - Make sure blast machine is adequately grounded. 8. Do not weld on blast machine, this voids approval. 9. Do not substitute Blastrite parts or modified equipment in any way.

2 1.0 INTRODUCTION Description: Thompson Valve The Thompson Valve 1 is an air-actuated metering valve designed to meter abrasive with precision. When air is sent to the valve, the valve opens, allowing blasting to begin. When the air signal is interrupted, the valve returns to the closed (off) position, the abrasive flow is stopped and blasting ceases. When installed, operated and maintained properly, the THOMPSON VALVE 1 will prove to be a dependable and performance enhancing component in your blasting system. The air-actuated design of the THOMPSON VALVE 1 requires a minimum of 70 psi and has a maximum pressure rating of 125 psi. Operational Requirements Extensive design and field-testing have proven the THOMPSON VALVE 1 to be effective and durable under intended use conditions. The following are common mistakes, which cause safety hazards: Improper remote controls used in conjunction with the THOMPSON VALVE 1 Improper maintenance Improper disassembly and/or incorrect reassembly. Improper installation of the unit Operating Instructions The THOMPSON VALVE 1 is an important component of the blasting system. For best performance and safety, follow these guidelines: Before using: Inspect all control line hoses verifying they are not cracked, abraded or damaged. Inspect THOMPSON VALVE 1 components, ensure there are no cracks, leaks or debris in the valve. Verify the pipe nipple and plunger are intact and not worn. The components are made of erosion resistant materials for durability, however the nature of abrasive blasting will cause these items to wear over time. During use: Monitor the control air line to verify the flow can not be interrupted, route the hose in a location free from traffic and severing hazards. Ensure the air/abrasive mix is correct (see Blue Flame section of this manual). To adjust abrasive flow, disconnect control air flowing to the valve and turn knob counterclockwise to increase abrasive flow and clockwise to decrease abrasive flow. NOTE: Control air must be disconnected.

3 Troubleshooting If your THOMPSON VALVE 1 fails to function properly, check the following: Symptom Cause Action THOMPSON VALVE 1 fails to actuate Improper air supply Inspect for restrictions and increase air pressure (70 TO 125 PSI). Damaged piston gasket or plunger seal. Replace (P/N s and 60919). Malfunctioning remote controls. See respective operator s manual for troubleshooting. Incorrect controls or malfunctioning control switch. Replace and/or see respective operator s manuals. Clogged abrasive feed area. Improper Lubrication Clean out abrasive and debris. Apply light coating of lithium based grease to cylinder walls. Damaged/Worn Spring Replace (P/N 60913). Vent port in side of cap is blocked Clean vent port with paper clip or toothpick Abrasive Flow Continues (when remote is released) Worn or damaged sleeve, plunger or plunger seal Replace any or all of the three (P/N s or and 60919). Obstruction keeping plunger from closing Remove any obstruction from inside of valve Malfunctioning remote control system See respective operator s manual Air pressure set to high Set air pressure at 70 to 125 psi. Vent port in cap is blocked Clean vent port with paperclip or
